Port F Data Direction Register (PFDDR)
Modes 4 to 6
Mode 7
PFDDR is an 8-bit write-only register, the individual bits of which specify input or output for the
pins of port F. PFDDR cannot be read; if it is, an undefined value will be read.
PFDDR is initialized by a reset, and in hardware standby mode, to H'80 in modes 4 to 6, and to
H'00 in mode 7. It retains its prior state in software standby mode. The OPE bit in SBYCR is used
to select whether the bus control output pins retain their output state or become high-impedance
when a transition is made to software standby mode.

Modes 4 to 6
Pin PF7 functions as the output pin when the corresponding PFDDR bit is set to 1, and as an
input port when the bit is cleared to 0.
The input/output direction specified by PFDDR is ignored for pins PF6 to PF3, which are
automatically designated as bus control outputs (AS, RD, HWR, and LWR).
Pins PF2 to PF0 are designated as bus control input/output pins (WAIT, BREQO, BACK,
